According to the British " Daily Mail " report, in a new study, scientists found that an asteroid with a diameter of 10 kilometers will hit the Earth. This is the largest impact event observed by astronomers so far.
The research comes from NASA astrophysicists Stephen Rosenz and Michael O'Sullivan.
This study conducted observations of near-Earth asteroids. These near-Earth asteroids are considered hazardous asteroids that could threaten life on Earth.
Over the past 40 years, astronomers have detected thousands of near-Earth asteroids, and these are all "uninvited guests" from outer space. This celestial body is called a "near-Earth object" (NEO), which refers to a near-Earth object less than 100,000 kilometers away from our earth.

Beijing time on March 20, according to foreign media reports, the threat from asteroids is becoming more and more serious. Space probes are also constantly approaching asteroids, detecting and tracking them, trying to find out their sources.
If these targets are indeed found in the next few years, will we be able to better understand how they formed and what impact they will have on our planet?
According to foreign media reports: NASA expects to discover new threats from space around 2030. NASA has begun studying potential threats over the next 100 years.
When you see a huge object flying down from the sky, do you feel scared?
"In space, people know that asteroids are dangerous," the NASA researchers explained. But in reality, when an asteroid hits Earth, the impact can be devastating.
Because when a comet hits an object within Jupiter's gravity , they can cause a catastrophic eruption. That's why many NASA and other space agencies are trying to study possible dangerous events.
NASA is currently studying the impact of asteroids hitting the Earth and determining whether they pose a serious threat to the Earth.
Hundreds of such asteroids have now been detected: In the past two years, NASA has detected and tracked a total of more than 400 celestial bodies that may pose a threat to the Earth - including 1,000 near-Earth objects and 1,000 near-Earth targets - more than half of which were discovered in July 2020.
But it’s worth noting that these targets are not that far away: more targets from space will be discovered in the future.
How likely do you think an asteroid is to hit the Earth?
So, the question is, do you think these asteroids will hit the earth in the next 100 years? There is no doubt that we are discussing this.
If the probability of an asteroid colliding with the Earth is 50%, then a devastating disaster will occur. Therefore, if this happens, it will be difficult for humans to survive.
But there are things we can do to prevent this from happening. With NASA's data and calculations, we can understand the consequences of these objects colliding with Earth. Over the past 20 years, scientists have brought approximately 3,000 asteroids from space to the Earth's surface. But that's not good enough because they're still flying in the atmosphere.
Is it possible to bump this planet into a position you want?
If you want to live on Earth, you will no doubt be told that the probability of an asteroid hitting the Earth is 1 mile per second.
But that doesn't mean it doesn't have a possible location, so you'd still have to pay attention to how these asteroids could be knocked into another planet, like we might see in the asteroid belt between Mars and Jupiter .
If these asteroids are indeed discovered somewhere, it will have a major impact anywhere on our planet.
For example, if an asteroid about 1 mile (2.4 kilometers) in diameter hit Earth, it would be destroyed 10 miles below the surface. This is catastrophic for all of us – because the damage it causes can be devastating. So it's hard to predict in the long term.
What can you do for the Earth to prevent this huge object from hitting the Earth, or at least reduce the damage it would cause if it hits the Earth?
We need to understand asteroids, which is the result of the joint efforts of scientists and aerospace engineers. The chance of an asteroid hitting Earth depends on the asteroid's size, orbit and the degree of threat they pose to life on Earth.
But if these asteroids collided with the Earth in some way, we would have the opportunity to change its orbit, thereby reducing its impact and slowing its impact.
However, we cannot rule out something like this happening within the next 100 years, as it may take decades to fully understand how these objects were formed.
Although NASA has developed a new generation of detectors, this is not enough to eliminate the threat. Despite these difficulties, there are still things we can do to protect our planet.
What can we do if we want to prevent this from happening?
We know that there are many asteroids that will collide with the earth. The largest of them hit the Mackay region of New South Wales, Australia, in September 2006. At the time, an asteroid set off warnings before impact, but caused no damage as it veered off course. Unfortunately, the impact completely leveled the area.
Therefore, scientists have been studying how to avoid such things from happening, but there is currently no effective solution.
But if we can control the frequency and distance of asteroids hitting Earth, this may be the only way to avoid the worst-case scenario.
What can we do to reduce the impact of asteroids approaching the Earth, or to avoid them from us.
What can we do to stop them? First, a better understanding of how to calculate the orbits of asteroids is needed to ensure they don't crash into Earth in the coming decades.
Secondly, we must better protect the earth in the solar system. For example, if an asteroid collided with another asteroid in low Earth orbit, they would not have enough time to destroy it.
But we must not forget: the formation of asteroids is a long but complicated process. If one day it hits a planetary system and causes a huge explosion, will it produce greater energy than imagined?
Warning about future asteroid impacts
That doesn’t mean we don’t have other ways to prevent them. In fact, this is also one of the ongoing tasks of NASA.
That is to help space exploration by launching more spacecraft so that they can orbit around the earth.
If we know the type, size and speed of the asteroid, then we can respond in advance. NASA is developing a new system to identify potential threats and issue alerts.
For example, the spacecraft will be activated when an asteroid about 10 kilometers (5 miles) in diameter approaches Earth.
If it is very close, it will send a signal into space and leave the Earth within seconds. The spacecraft then sends an alert to everyone around it, alerting them to impending danger.
